Fragmented QRS complex as a predictor of coronary artery disease in patients with acute coronary syndrome (A study from Egypt)

摘要

Methods: Two groups according to the presence of fQRS in ECG. Results: fQRS has higher sensitivity for LAD, LCX &RCA, more specific for LAD. Conclusions: fQRS is a good, simple, applicable positive test to predict the presence of significant CAD in acute coronary syndrome (ACS), even without enzyme elevation. Theoretically, fQRS is due to heterogeneous myocardial electrical activation from regional ischemia, myocardial fibrosis or scar. We aimed to detect if the presence of fragmented QRS complex in patient with acute coronary syndrome (ACS) can predict the presence of coronary artery lesion and to which extent in Egyptian patients.
